OBJECTIVES: To evaluate the effect of Z-spring appliance and clear aligners, used in anterior crossbite treatment, on dental plaque colonization in children.
METHODS: A 2-arm randomized controlled trial included 30 patients aged 7-12 years with anterior crossbite. Participants were divided into 2 groups: clear aligner (group A, n=15) and Z-spring appliance (group B, n=15). Dental plaque samples were collected at treatment initiation and completion, inoculated onto selective media, and analyzed for colony counts (cfu/ml) of Streptococcus mutans (S. mutans), Streptococcus mitis (S. mitis), Streptococcus salivarius (S. salivarius), and Candida albicans (C. albicans).
RESULTS: In group A, S. mutans counts significantly increased (p=0.006), while C. albicans counts decreased (p=0.039). In group B, S. mutans counts significantly decreased (p=0.002). No significant changes were observed in S. salivarius or S. mitis counts in either group.
CONCLUSION: Short-term clear aligner use in children increases S. mutans colonization, suggesting a potential risk for dental caries with prolonged treatment. Early preventive measures are crucial to mitigate this risk and ensure better oral health outcomes.ClinicalTrials.gov Reg. No. ID: NCT06858033.
